Before I pull the trigger on some of these I wonder if you guys can answer a few questions as information on them seem so scarce.
1. Is the power button just to turn them on and they turn off automatically after no signal? Or do you have to manually turn them off?
2. How long do they stay charged for? I had some LG glasses for an LG plasma that would only stay charged for 3 hrs. Should I be expecting the same?
